To all whom t may concern.-

Be it known that we, FREDERIC G. STOREY, residing in Cambridge, in thecounty of Middlesex, EDWARD R. ANDREWS and JOHN P. CUSHING, residing inBoston, in the county of Suffolk, and HOWARD F. EATON, residing inQuincy, in the county of Norfolk, State of Massachusetts, have inventedan Improvement in Electro-Protective Systems, of which the followingdescription, in connection with the accompanying drawings, is aspecification, like letters and figures on the drawings representinglike parts.

This invention relates to an electrical protective system especiallydesigned and adapted for the protection of safety deposit vaults, banksand like institutions.

One feature of this invention consists in a novel construction andarrangement of elec trical apparatus and circuits, whereby the safetydeposit or other institution is placed uuder police protection for apredetermined interval of time, during which time any attempt to openthe vaults will be automatically made known and recorded at the policestation, and preferably will also be recorded within the vault and inthemain or snperintendents office of the institution, the particularbuilding in which the attempt is being made to open the vault beingidentified in the police station by a number, which will be hereinafterdesignated as the building number.

Another feature of this invention consists in constructing the apparatusas will be described, so that the building to be protected may bedisconnected from the police station, and the plant operatedduringbusiness hours for purpose of exhibition without sending an alarmto the police station.

This/invention further consists in a novel arrangement of test circuitsand apparatus operated thereby, by which the condition of the operativecircuits may be made known at the time of closing the safety depositvault or bank, the system being arranged so that each circuit isrequired to be tested before the circuit to the police station can becompleted.

Another feature of the invention consists in a novel arrangement wherebythe failure of any circuit to respond to its test is audibly indicatedwithin the building.

This invention further consists in a novel combination of switch boardto which all the operative circuits of the system are connected in suchmanner, that the arrangement or connection of circuits may be transposedor rearranged to prevent illegal tampering with any of the.circuits, thecombination switch board being constructed so that when once closed, anyattempt to open the same by an unauthorized person would be recorded atthe police station, which for the purpose of this invention may beregarded as the central offlee of the system.

Safety deposits. banks and like institutions, as now commonlyconstructed, have their vaults or receptacles for valuables located in achamber, which is usually protected b v a strong iron grating or grillhaving a door, which is usually guarded by a policeman.

One of the features of this invention consists in providing the door ofthe grill or grating with an electrically controlledflock, which isadapted to be automatically operated and locked by an attempt to open adoor of any one of the numerous vaults located within the chamber,which-closing of the circuit automatically transmits an alarm to thepolice station. The automatically operated lock is also designed to beoperated by manually controlled or operated switches or push buttonsdistributed about the building. These and other features of thisinvention will be pointed institution to be protected; Fig. 2, a dia#gram of circuits showing two message recordking instruments and twomessage timing instruments, one set of which is designed to be locatedWithin the main vault, and the other set in the superintendents office;Fig. 3, a diagram of circuits illustrating the test portion of thesystem; Fig. 4, a diagram ofcircuits illustrating the circuitscontrolled by the testing apparatus; Fig. 5, a diagram of circuitsillustrating one way of connecting the circuits to the combinationswitch board; Fig. 6, a diagram of circuits illustrating a differentarrangement or combination of the circuits shown in Fig. 5; Fig. 7,adiagram of circuits illustrating another arrangement or combination ofthe circuits shown in Fig. 5; Fig. 8, adetail to be referred to; Fig. 9,a detail in perspective of the form of test magnet preferred by me; Fig.10, a detail of the police register to be referred to; Fig. 10, a detailof switches to be referred to; Fig. 11, a detail of the messagerecording strip located Within the superintendeuts oliice; Fig. 12, adetail showing the manner preferred by us of completing the electriccircuit Within the vault; Fig. 13, a sectional detail of the circuitterminals operated by the vault door, the section being taken on theline 13--l3, Fig. 14; Fig. 14, a sectional detail to be referred to,taken on theline let-lli, Fig. 13, and Fig. 15, a detail of thecombination switch board to be referred to. Referring to Fig. 1,thesignaltransmitting apparatus by which the signal indicative of thebuilding or institution to be protected is transmitted, is herein shownas an ordinary break-Wheel (t of any usual or Well-known construction,such as noW commonly used in electric signal Work, the said break-Wheelbeing operated by a motor mechanism, which may be a clock mechanism ofany usual or well-known construction, and which in the present instance,is represented by a gear (L connected with a shaft or arbor (L2 havingupon it a detent disk (L3, with which co-operates a finger (LLl on thepivoted armature lever (L5 ot' an clectro-1nagnet af. The magnet a6,which will be hereinafterdesignated by us as the starting magnet for thesignal-transmitting mechanism, is included in the circuit of a battery(L7, one end of the coil of the said magnet being preferably connectedby Wire (L8 to a terminal (L9 secured to a switch board (L10, and theother end (112 of the coil of the magnet (L6 is connected to one end(L13 of the coil of an electro-1nagnet (L14, the purpose of which willbe hereinafter described, the other end (L15 of the coil of the magnet(L14 being connected to a terminal (L16 on the switch board (L10. Thebattery (t7 has its positive and negative poles connected respectively,as herein shown, by wires a (L18 to terminals (L19 UL20, which arerespectively connected to terminals 0L21 al" by removable Wires (L22(L23. The terminal (L21 on the switch board (L10 is connected to thefront stops of, preferably, a series of electro-magnets or relays, inthe present instance marled l, 2, 3, and 4, indicating four circuits asincluded in the present system.

The front stops referred to, and herein marked 6, 7, 8, and 9, arerespectively connected by branch Wires l0, 12, 13 and 14 toa Wire (L24,connected to the terminal (L21 of the switch board (L10. The armaturesof the relays 1 to e inclusive, which are marked 16, 17,

18 and 19, are connected by branch wires 20, 21, 22, 23 to a Wire (1,25,joined to a contact or terminal (L2G co-operating with a like terminal(1,27, Which latter is joined by wire (L28 to one member a2" of anormally closed time-governed circuit controller A, the co-operatingmember (L30 of which is connected by a wire (L31 to a terminal (L32 onthe switch board, the said terminal (L32 being joined by Wire (L33 tothe terminala. The terminals a2 (L27 have (zo-operatingwith them amovable member or connecting device, represented as a contact piece orblock (L40 on a pivoted arm 0L, normally engaged and held elevated by anarmature (L42 of an electro-magnet (L43, for a purpose as Will bedescribed.

The terminal @32 on the switch board has ,connected to it a second wire(L44 to which are connected the members 30, 3l, 32, 33, of normally opencircuit controllers or push buttons, the co-operating members 35, 36,37, 3S of which are connected by the wire (L45 to a terminal a on theswitch board (L10, which latter terminal is connected by Wire (L4T tothe terminal (L21.

The normally closed circuit controller A referred to, is designed toremain closed until opened at a predetermined interval of time, whichmay be selected by the superintendent or other person having charge ofthe system, and in the present instance, the circuit controller A isrepresented as being adapted to be opened by a lug or projection (L50 ona disk (L51, mounted on a shaft 0.52 adapted to be rotated in unisonwith the hour hand of a clock mechanism A of any usual or Well-knownconstruction, the disk (L51 being capable of being set by hand so as tobe rotated by the clock mechanism, to bring the lng or projection (L50into contact with the member (LEU of the circuit controller, at apredetermined hour or interval of time at which it is desired to openthe circuit of the starting magnet controlled by the relays, therebypermitting the vaults or other receptacles included in cir cuit with therelays, as will be described, to be opened Without giving an alarm atthe police station.

Instead of the particular form of circuit controller herein shown, Wemay employ any other desired or suitable construction capable of actingupon the member (L29 at the desired interval of time. Thesignaltransmitting wheel (L is designed to operate a circuit leading tothe central office or police station A2, and preferably to also operatea local circuit within the main vault in which the signaltransmittingmechanism is located, and a second circuit or branch of the localcircuit eX- tended to the superintendents office.

In the present instance, the signal transmitting Wheel is shown asadapted to operate one member or pen b of a circuit controller, Whichco-operates with a second member or pen b. The member b ofthecircuitcontroller is connected by Wire b2 to one end of the coil of anelectro-magnet or relay b3, the other end IOO IIS

IZO

of the coil of the relay 53 being joined by wire 51 to a terminal 55 onthe switch board @15, the

terminal 55 being connected by a removable.

wire 55 to a second terminal 57 to which one pole of the battery 58 isjoined by wire 55, the other pole of the said battery being connected bywire 515 to the ground G. The member 5' of the circuit controlleroperated bythe signaltransmitting wheel d, is connected by wire 512 andits branches 513 511 to terminals 515 515, with which co-operaterespectively the movable members 517, 518 of switches, which may be ofany usual or well-known construction, and which are herein representedas pivoted, as at 512, 525, to a suitable base or support 521, shownseparately in Fig. 1 05. The switches 517 515 are preferably connectedtogether to be moved simultaneously by rods 522, 523, joined to a crossbar 521 provided as herein represented with a roller or projection 525,for a purpose as will be described. The switch 517 is normally incontact with the terminal 515, but when operated,it is adapted to makecontact with a terminal 525, connected by Wire 527 to the terminal 55 onthe switch board a15. The switch 518 is joined by wire 528 to a terminal525 on the switch board @15, which terminal is connected by a wire 535to a terminal 551, joined by wire 532 to one pole of the battery 533,the other pole of which is joined by wire 551 to a terminal 535,connected by wire 535 to a terminal 557, joined by wire 558 to theterminal 55. The switch 517 is connected to the receiving apparatus inthe police station 'A2, the said switch being herein shown as connectedby wire 515 to-acut-out apparatus 511 of any usual or well-knownconstruction, the said cut-out being connected by two wires 512 513 to amovable member 511 of a key or circuit controller K located in thepolice station, the stationary member 515 of which is connected by wire515, to one end of the coil ot' the magnet 517 of a tap bell 513 of anyusual or well-known construction, the other end of the coil of themagnet 517 being connected by wire 515 to one end of the coil of theelectro-magnet 555, having the other end of its coil connected-by wire551 to the ground G. The magnet 555 may be the printing magnet of aregister or record apparatus of any usual or well-known construction,such as now commonly used in police and tire-alarm systems, to recordmessages upon the tape 552, the armature 553 of the said magnet beingprovided with a stylus or pen551.

In practice, the wires 512, 513 form a doublev path for the messagebetween the building to be protected and the police station or centraloffice, so that in case of accident to one of the Wires, the signal willstill be received over the other wire. In the normal condition of theswitches 517, 515, as represented in Fig. 1, the signal-transmittingapparatus located in a building to be protected, is adapted to transmitits signal to the police station over the ground circuit, and thecircuit for this signal may be traced as followsz4 minal 57, wire 55,terminal 55, wire 51, relay 53, wire 52, to terminal 5 of the circuitcontroller co-operating with the breakfwheel a, v

terminal 5', Wire 512, branch 515, terminal 515, switch 517, Wire 515,through the cut-out 511, through the double wires 512 513 to key Kin thepolice station, thence through the police bell magnet 517 andregistermagnet 555 and wire 551 to the ground G', thence back to theground G and by wire 515 to the positive pole of the battery 55. Thesignal tr-ansmittted by the signal mechanism or break-wheel a, which inthe presentinstance is formed to transmit the number 333, is alsoreceived by the relay 55 controlling a local circuit as will bedescribed, including initpreterably two message recordinginstruments B B(see Fig. 2) which may be ot' any usual or well-known form ofregistering mechanism, such as now commonly used in fire and policesignaling work, one of the said registers as B, being located in themain vault, hereinafter designated the steel vault, and the other as B,being locatedin the su erintendents otce. Theregisterinfrmech- D e t endof its coil connected by the wire 555 with the wire 555. The terminal551 is connected by a removable wire 555 to a terminal 557, joined bywire 558 to one pole, herein shown as the negative pole, of the battery555, the `other pole of which is connected by wire 575 to a terminal 571on the switch board w15, which terminal isjoined by a removable wire 572to a terminal 573, connected by a wire `571 to the armature 575 of therelay 53, the said armature co-operatingwith ya back-stop 5 75 joined bywire 577 to a wire 575, connected to one end of the coil of an operatingmagnet IOO for the bell 575, the other end of the coil ofy ters B B haveco-operating withl them time n,

stamp mechanisms B2 B5, which may be of any usual or well-Knownconstruction and which are operated from the registers. The time stampmechanism B2 has its electro-magnet c joined by wire c' to one terminal`or pen c2 of a normally open circuit controller, the other terminalorpen c3 of which, is connected by wire c1 to a wire c5 leading to onepole of the battery c5, the other pole of which is connected by wire c7to wires o5 c5, the wire o5 being connected to one end of the coil ofthe electro-magnet c for the time stamp B2, while the wire o0 isconnected to the end of the coil of the electro-magnet C40 of the timestamp B0, the. other end of the coil of the magnet 040 being joined bywire 010 to one terminal c10 of a normally open circuit controller, theco-operating member 044 of which is connected by wire 015 to the wirec5. The normally open circuit controllers governing the operation of thetime stamps B0B3, are adapted to be closed during the movement oftheregister to record a signal, by suitable devices, herein shown asdisks C40 c17 provided with projections 040 C40, the said disks beingmounted upon suitable shafts of the register so as to be revolved whenthe register is started.

Each break in the main line circuit occasioned by a tooth or projectionon the breakwheel a, demagnetizes the relay Z10, and its armature Z175is withdrawn by its retractor C00 into engagement with the back-stopZ170, thereby closing the circuits of the magnets Z100 Z10l for theregisters, and causing a record to be made upon the tapes C04 a02 afterthe manner now commonly practiced in police and tire alarm systems. Thecircuit for the starting magnet Z100 of the register B may be traced asfollowsz-from the positive pole of the battery Z100 by wire Z170,terminal Z174, removable wire Z102, terminal Z100, wire Z174 to thearmature Z170, thence by the back-stop Z170, wires Z177, Z100 throughthe magnet of the bell Z170, thence by wire Z100 through the magnetZ100, thence by wires Z100, Z103 to the terminal Z104, through the wireZ100, terminal Z107 and wire Z100, to the negative pole of the battery.

The circuit for the starting magnet Z10l of the register B may be tracedas follows:- from the positive pole of the battery Z100 to the armatureU5 as above described, thence by the back-stop Z100, wires Z107, Z181 tothe terminal Z102, thence by the wire Z100, terminal Z104, wire Z105,through the magnet of the bell Z100, wire Z100, magnet Z101 and wiresZ105, Z103 to the terminal Z104, thence to the negative pole of thebattery through the wire Z100, terminal Z10T and wire Z100. It will thusbe seen that at each opening of the circuit containing' the relay Z10,occasioned by a tooth or projection of the signal transmitting mechanismor break-wheel a, the magnets of the registers Z100 Z101 are energized,and a record of each impulse or break is denoted upon the recordingtapes C01 000 after the manner illustrated in Fig. l1 on the tape 000,each break being indicated by a substantially short mark or dash.

The time stamps B2 B3 are operated by the starting of the register torecord the time at which the signal indicated by the break-Wheel a, isreceived. In order that a record maybe made of the opening of the doorsof the building or bank after the latter has been closed to itsdepositors and the protective system set in operation as will bedescribed, the different doors of the building are provided with circuitcontrollers connected in circuit with the operating magnets of theregisters B B', and

in order to identit y the particular door, which has been opened, Weprefer to construct the circuit controllers of the diiterent doors insuch manner as to identity or designate the particular door opened. Thismay be accomplished after the manner shown in Fig. 2, wherein arerepresented three circuit controllers B4 B5 B0, the circuit controllerB4 consisting of the member 000 provided with a single projection 004adapted to co-operate and make contact with a pen or member 000, whenthe door is opened. The circuit controller B5 consists of a similarmember C00 provided with two projections C04 co-operating with a penC00, and the circuit controller B0 is represented as consisting of themember 00T provided with three projections 000, which co-operate withthe contact pen or member 000. One member of each of these circuitcontrollers is attached to or connected with a door, and the othermember may be attached to the casingot the door, so that when the dooris opened contact will be made between the contact pen or spring and thetooth or projection on it-s cooperating member.

The circuit controllers B4 B5 B0 are connected in circuit with thebattery Z10fl and with the magnets Z100 Z104 of the registers by theWires C40 C41, connected respectively to terminals C40 C40 on the switchboard @40, the circuit terminals being joined by removable wires C44 640to terminals C40 047, connected respectively by wires 040 C40 to theterminals Z102 Z100. The members 000 C00 C07 of the circuit controllersB4 B0 B0 are connected as herein shown to the wire 040, by the wires C00004 000, while their co-operating members 002 C05 000 are connected bywires C00 004 005 to the wire 044. In order that the operation of theregisters by the opening of any one of the doors may be understood, Wewill describe the circuit completed by the opening of the door providedwith the circuit controller B4. Vhen the door is opened, the contact pencfzand the tooth or projection 004 are brought-into engagement, and thecircuit from this door may be traced from the positive pole ot thebattery Z100 by wire Z170, removable wire Z172 to the terminal Z100,thence by the wire C40, terminal (147, removable Wire C40, terminal C40,wires c, 053, contact pen C00, contact member 000, wires C00, 040, toterminal 040, thence by removable wire C44, terminal c40, wire 040 to aterminal Z100, where the current divides, part going through the wireZ104, the bell Z170, Wire 600, register magnet Z100, wires Z102 and Z103to the negative pole ot' the battery Z100, the other portion of thecurrent leaving the terminal D02 passing through the wire Z100, terminalZ104, wire Z100, bell Z100, wire Z107, magnet Z101 of the register B,wires Z100, Z100 to the negative pole of the battery. It will thus beseen that by opening the door provided with the circuit controller B4,the magnets Z100 Z101 are energized and the registers B B operated andmade to record one short mark or dash on the tapes c01c02,and at thesame time, the time stamp mechanisms B2 B0 are operated to record thetime at which the IOO ITO

door is opened. The short mark on the tapes 021 022 denotes that thedoor provided with the circuit controller B4 has been opened. It' thedoor provided with the circuit controller B5 1s opened, two marks ordashes are recorded upon the tapes of the registers, and will therebydenote that the door provided with the circuit controller B5 has beenopened, and if the door provided with the circuit controller B6 isopened, three marks will be recorde upon the tapes of the registers.

It is evident that each door of the bank or vault, if so desired, may beprovided with a circuit controller constructed to identify the door bywhich it is operated. It will be noticed that the opening operates onlythe registers and time stamps in the vaultand in the superintendentsoffice, and does not operate the police signal recording mechanism. Inthis manner an accurate record of the opening of the different doors ofthe institution after the latter has been closed and placed under policeprotection, is obtained, and in accordance with this invention, a recordof the cause or reason for opening any of the bank doors after hours,will be entered upon a suitable record book kept for that purpose,thereby enabling the superintendent or other proper officer to know thenumber of times each door has been opened during his absence, and thepurpose for which it was opened. In accordance with this invention, oneor more of the different safes containing the valuables to be protectedare included in separate circuits, each of which is provided with a mainor signal operating relay connected to a test relay. In Fig. 1, we haveshown one complete circuit for the relays 1 la, which circuit includesone vault, which, for in stance, may be supposed to be thev silver vaultrepresented as provided with two doors marked N D, S D, signifyingrespectively north and south doors of the said vault. The relays 1 1fLare connected in series as herein shown, and one end of the coil of therelay 1 is connected by wire d to a terminal d on the switch board 0.10,and the other end of the coil of the relay 1 is connected to one end ofthe coil of the relay\1a by wire d2, the other end of the coil of therelay 121 being connected by Wire cl3 to a terminal d4. The terminal dis joined by wire d5 to a terminal d6, connected by a wire (Z7 to aterminal cls, joined by wire di) to one pole of a battery d10, the otherpole of which is connected by wire d1 to a terminal (Z13, joined by wireC314 to a terminal (115, which is represented in Fig. 1, as connected bywire (116 to a terminal 0111 electrically connected by Wire Z151 to thenorth door, as will be described. The north door is provided with,preferably, three circuit controllers consisting of three movablemembers or rods 60, 6l, 62, and three' stationary members 63, 61, 6,5,which in practice are located in a suitable boXor case 66 shown indetail in Figs. 12, 13 and 14. The members or rods 60, 61, 62 are shownin Fig. 111, as movable in-a guide arm 67 and as encircled by,`

springs 68, which serve to remove or withdraw the members 60, 61, 62,from engagesouth door ot` the silver vault is equipped with like circuitcontrollers, consisting of the movable members 70, 71, 72, and thestationary members 73, 74, 75. We prefer to employ three sets of circuitcontrollers for each vault door and to arrange the same in multiple asshown in Fig. 1, to thereby guard against 1mperfect contact between themembers, thereby insuring a closing of the relay circuit when the vaultdoor is closed and locked. As represented in Fig. 1, the numbers 63, 64,65 on the north door are connected to a wire 80, and the members 70, 71,72, are connected to a Wire 8l, which, as shown, is joined to the wire8O by three wires 82, 83, 84,'which in practice, are located under thesidewalk and beneath the usual grating in said sidewalk. Instead ofthree wires, we may use only one, but we prefer to employ more than one,to avoid the circuit being opened, if one of the said wires shouldbecome accidentally broken. The numbers 73, 74, 75 ot' the south doorcontrollers are connected to a wire 85 leading to a terminal 86 on theswitch board 0,10, the said terminal being joined by a removable wire 87to the terminal d4. l

As represented in Fig. 1, the doors N. D. S. D. of the silver vault areclosed, and the circuit of the relays 1,1a completed, which circuit maybe traced as follows, vizz-from the positive pole ot the battery d10 bywire d12, terminal 113, Wire (114, terminal C115, wire dw, terminal d,wire CX18, circuit controllers to inclusive, wire 80, wires 82, 83, 84,wire 8l, controllers to 75 inclusive, wire 85, terminal 86, Wire 87,terminal d4, wire cl3, relays l, 1, wire d, terminal d', wire d5,terminal d6, wire CF, terminal d8, and Wire d to-the negative pole ofthe battery.

In order that the circuit of the relays 1, 11,`

may be completed for-purpose of exhibiting the system when the doors N.D., S. D., of the silver vault are opened during the day-time, anauxiliary battery d3@ is adapted to be included in circuit with therelays 1, 11, to energize the said relays, and thereby open the circuitof the signal transmitting mechanism between the armature 16 oftheirelay 1 and its back-stop 6. As shown in Fig. 1, the battery alsohas one pole, as for instance, the positive pole, connected by wire (131to a terminal d32 on the switch board d10, which terminal is joined by awire e133 to a terminal dsconnected by wire d35 to a terminal 0136 vonthe switch board b21, the said terminal having cooperating with itamovable member or switch di17 secured to the rod 623, the said movablemember being joined by wire C138 to the terminal d4. The negative poleof the battery d3@ is connected by wire Z39 to a terminal C740 on theswitch board 01,10, which terminal is ICO IIO

joined by a wire d to a terminal C142, connected l.

by wire d4B to a terminal d44 on the switch board b21, the terminal d4ihaving co-operating with it a movable member or switch d secured to therod or bar 1122, and joined by wire d to the terminal d6. The relays l,l are normally included in circuit with the doors of the silver vaultwhen the latter are closed and locked, but when the vault doors areopen, the relays l, l, become demagnetized until the switches (E37, d,are brought into engagement-With their co-operating terminals d3, d'1".With the switches CW, CX45 in contact with their co-operating terminalsCX36, (144, the circuit of the relays l, la, may be traced as follows,vizr-from the positive pole of the battery d3@ by wire d, terminal dsl?,Wire dis, terminal dm, wire F5 to terminal d3, thence by switch d, WireCFS, terminal d4, wire d3, relay l, Wire d2, relay l, Wire d, toterminal d', thence by wire d5, terminal d6, wire d4, switch C145,terminal d, wire d', terminal C142, Wire d, terminal d, and wire Z39 tothe negative pole of the battery CPO. It will thus be seen that therelays 1 l2L may be magnetized and demagnetized when the vault doors areopened, by closing and opening the switches d3?, e145, the test relaysl, 2a, doc., governing the operative condition of the signaltransmitting circuit as will be described.

Referring to Fig. 3, the relays la to 4 inclusive, directly govern fourtest circuits provided with circuit controllers orpush buttons, numbered1 to at to correspond to the test circuits and which may be used in thepresent instance to identify the different test circuits. It will benoticed by reference to Figs. l and 3, that the test circuits l to etare governed by the test relays l to 4, and that those relays areincluded in the four circuits governed by the doors of the vaults orreceptacles to be protected, so that, if the test circuits are inworking condition when the vaults are closed, the circuits including thevaults are also in Working condition.

One feature of this present system is to enable the vault circuits to betested after the vault doors are closed, without operating` the signaltransmitting mechanism, and to render it obligatory upon the personmaking the test of the vault circuits, to test all the circuits beforethe system can be turned over or connected in circuit with the policestation or central oice. To accomplish this result, the test circuitsinclude the armatures 50, 51, 52, 53, of the relays l to 4 inclusive,and also the front stops 5t, 55, 56, 57 for said armatures. The testcircuits further include one set of electro-magnets lb 2l 3l 4b, and asecond set of electro-magnets lc, 2, 3C, 4c, for a purpose as will bedescribed.

The electro-magnets lb to 4b inclusive may and preferably will be madesubstantially as shown in Fig. 9, each magnet being provided with anarmature e, governing the action of a circuit controller shown as a bare of conducting material, pivoted as at e2 and provided with asubstantially Wedge-shaped piece e3, and having its free end notched toenter into a slot e4 in the end of the armature e, the said bar beingheld up by the said armature in an old and patented form, butinsteadofthe particular construction shown, We may use any othersuitableconstruction. The bar e as represented in Fig. 9, has extended from itsopposite sides conducting rods e5 e6, which, in the normal or elevatedposition of the said bar, co-operate with circuit terminals e7 e8, andthe wedge e3 when the bar e' is released by the attraction of thearmature e, co-operates with terminals ci elo, the said ter minals beingsecured as shown in Fig. 9 to a suitable base cl2. For the sake ofclearness, we have, in Figs, 3 and 4, identified the circuit terminalscT e8 e el() employed with the diiierent test magnets, by prexing thenumber of the test circuit in which its magnet is located. The circuitterminals e7 e8 corresponding to the different test circuits, arearranged in multiple with one another in a circuit including anelectro-magnet cl3, which will be hei-einafter specified as the out oforder magnet, while the terminals ei el corresponding to the differenttest circuits, are arranged in series in a circuit including a magnet e,to be hereinat'ter designated as the in order magnet, and also includingthe signal-transmitting circuit-controlling magnet a.

The magnets lc to etc inclusive, together with the magnets @13 e, inpractice, are located in a suitable case, not shown, but which is preferably located in the vault room or chamber, while the magnets lb to 4inclusive and the magnet am are located in the main vault, which may bedesignated as the. steel vault. The magnets lc to 4-0 are provided witharmatures having co-operating with them circuit controlling drops orbars, which may be ofthe same construction as the test magnet dropsshown in Fig. 9, except that the pins or rods e5 e6 and circuitterminals e7 es are omitted. The circuit controlling wedges e operatedby the magnets lc to l@ inclusive co-operate with terminals e" @10,which may be distinguished from each other and from the terminalsgoverned by the test magnets l" to et, by prefixing the symbol of themagnet lc to in inclusive, which governs the said terminals, clearlyshown in Fig. et. The circuit controlling wedge e3 operated by the outof order magnet cl3 co-operates with circuit terminals 620 621 of alocal circuit including an audible signal or bell @22, preferably of thevibratory or continuous ringing type, by which a Warning is given thatthe circuits are not in order, the said local circuit including abattery @23, herein shown as connected to the switch board al, one poleofthe battery e23 being connected by wire e24 to a terminal c25 on theswitch board am, the said terminal being joined b v Wire @26 to aterminal 627, connected by wire 92S to the circuit termi nal @20, theterminal 621 being connected by wire c2, including the magnet of thebell egg, to a terminal e30 on the switch board d10, the terminal e30being joined by Wire ci to a terminal 632 connected-by wire @33 to thenegative pole of the battery 623.

As represented in Fig. 3, each test circuit is provided with its ownbattery marked D D2 D3 D4, connected to the switch board d10, and thecircuit of the said batteries is governed at two points, namely, at thepush buttons or controllers s to s4 inclusive, and at the armatures 50to 53 inclusive. inasmuch, as the circuit connections of the four testcircuits are the same, we will describe but one in detail, namely, testcircuit No. l. The battery D has one of its poles, shown as the positivepole, connected by wire 640 to a terminal e41 on the switch board am,which terminal is joined by wire @42 to a terminal e343 connected bywire 644, to one member of the switch or push button s', the othermember of which is joined by wire c45 to one end of the coil of themagnet 1C, the other end of the said coilbeing connected by wire e46 tothe front stop 54, with which co-operates the armatureO connected bywire e247 to one end of the coil of the magnet l", the other end of thesaid magnet being connected by wire 48 to a terminal 649 on the switchboard am, the terminal @49 being joined by wire @50 to a terminal 651,connected by Wire @52 to the negative pole of the battery D. It willthus be seen, that as long as the circuit ot' the test relay la isclosed, the armature 50 will be attracted and will make contact with itsfront stop 54, and the circuit of the magnets lb and l, Will be closedat that point but will remain open at the push button orswitch s. TvVhenit is desired to test the circuit ot' the relay l, the push button orswitch s is closed by the operator, and if the circuit of the test relayln is closed and in operative condition, the circuit of the battery Dwill be completed, and the magnets lb 1c' energized, but if the circuitof the test relay ltL is defective, such as by a break in a circuit wireor by a weakening of the battery, the

circuit of the battery D will not be completedv when the switch or pushbutton s is closed. The circuit of the battery D may be traced asfollows: from the positive pole by wire 640, terminal @41, wire @42,terminal 943, wire 644, switch button s', wire c45, magnet lc, wire e46to the front stop 54, thence by the armature 50, wire 647, magnet lb,wire @48, terminal @49, wire @50, terminal 651 and wire 652 to thenegative pole of the battery.

' The circuits of the batteries D2, D3, D4, are tested by closing thepush buttons or switches s2, s3, s4 in the same manner, andas eachcircuit is closed at its push button, the armatures e of the dropmagnets lb, 2b, 3", 4b, are attracted7 and the circuit controlling barse co-operating with the said armatures are released, the wedges eszonthe said bars dropping into engagement with the circuit terminals e9, ewof the respective test circuits. At the same time, the armatures cot theannunciator magnets lc, 2C, 3, 4C, which are secured to the test board,are also attracted, and release the circuit controlling bars e co-oper.-

ating therewith, which bars fall and their v preferably inscribed withthe words In order, will visually indicate that all the test f circuitsare in working condition, and at the same time the armature of themagnet 01,43 will drop and make contact with the circuit terminals Q26,0,27, thereby completing the circuit ot the starting magnet a6 for thesignal transmitting mechanism at all points except between the armaturesof the relays l to 4 inclusive and their back stops 6 to 9 inclusive, asrepresented in Fig. l; so that if a relay in any of the circuits, as forinstance, therelay l, should become demagnetized by the opening of itscircuit, its armature Willbe brought into contact with its back stop,and ythereby complete the circuit of the starting magnet a6,

which, in turn, attracts its armature a5 and t Starts thesignal-transmitting mechanism in operation and transmits the numberlndicated by the teeth or projections on the break-wheel a, to thepolice station, and also to the super.

intendents oftice and back to the receiving instrument in the main orsteel vault.

The circuit of the magnet 0,43 shown in Fig. 4 includes in it a batteryfhaving one of its poles, as for instance, the positive pole, connectedby wire f to a terminal f2 on the switch board alo, which terminalisjoined by a wire f3 to a terminalf, connected by wire f5 to one end ofthe coil of Ithemagnet 01,43, the other end of the coil of the saidmagnet being joined by wire f6 to the circuit terminal 4 e9 connected bythe wedge e3 on the circuit controlling bar of the magnet 4b to theterminal 4 e10,which is joined by Wire f7 to the terminal 3 e9,electrically connected through its co-operating wedge e3 with theterminal 3 @10, joined by wire f8 to the terminal'2 e9, electricallyconnected'through its co-operating Wedge c3 with the terminal 2 ew,which is joined by Wire f9 to the terminal l e9, electrically connectedthrough its wedge e3 to the terminal l elo, thence by wire-f10 to theterminal 4c e9, through its wedge to the terminal 4c ew, thence bywire]12 to the terminal 3c e9, through its connecting wedge to theterminal 3" ew, thence by wire f13 and the terminal 2 e and its Wedge c3to the terminal 2c ew, thence by wire f14 to the terminal 1C e9, throughits connecting wedge to the terminal lc @10, thence by Wire f15 throughthe electromagnet e, thence by wiref116 to one member ICG of the switch55, thence through the other.

the wire f1", terminal f2", and wire f21 to they negative pole of thebattery f. `It will thus be seen that the circuit terminals controlledby the electro-magnets lc to 4 inclusive, and by the electro` magnets lbto et" inclusive, are arranged in series in the circuit of the inagnetC443, and iffor any reason, any7 one of the circuits connected to thevaults or receptacles to be guarded, which circuits include the relays lto LL inclusive and the test relays ln to a inclusive, should be ont otorder, as by the breaking oi a connection or by the weakening of itsbattery, the armature ot the test relay included in the particularcircuit so disabled, would be retracted away from its front stop andthereby open the test circuit corresponding to the particular circuitthus disabled.

Referring to Fig. 3, we have shown the arma iure 553 of the test relay/a as withdrawn from engagement with its front stop 57, therebyindicating that the circuit Ain which the test relay 4 and the relay 4are included, is out ot' order. lVhen one of the circuits includ ing therelays l to 4c and I to et inclusive, is out of order, which, in thepresent instance, is indicated as the circuit including the test relayit, the magnets 4C and Lib will not be energized when the operatorcloses the fourth test circuit at the push button or switch s1; and inthis case, the circuit controlling bar e Operated by the magnet Ib willremain in its normal position, with the pins e5 ein engagement with thecircuit terminals e eT et e8, so that, when the operator closes theswitch or push button 35, the circuit of the out of order magnet cl3will be completed through the said terminals, and the in order magnetwill not be energized, nor Will the magnet als be energized to completethe circuit of the starting magnet a6. The circuit of the out of ordermagnet cl3 in this case may be traced as followsz-from the positive poleof the battery fby wire f', terminal f2, wire f3, terminal f4, wire f22, and branch Wirej`23, termin al 4 e8, pins e, e5, terminal 1i e7,branch wire f24, wire f25, connected to one end of the coilot" themagnet cl3, thence by wire f2@ connected to the wire f1, thence by wirefw through the switch S5 and wiref17 tothe terminal fis, thence by thewire fw, terminal f2), and wire f21, tothe negative pole of the batteryf. The magnet cl3 being energized, attracts its armature and releasesits circuit controlling bar e', the wedge e3 of which is brought intoengagement with the terminals @20, 621, of the local circuit containingthe battery @23 and the magnet ofthe bell @22. This local circuit istherefore closed by the energizing of the magnet cl2, and remains closeduntil positively opened by lifting the circuit controlling bar e of thesaid magnet. In this Way, an audible alarm is given that one of thecircuits is out of order,

and the particular circuitis identified by the drop of the magnet on thetest board remainingin its normal position, which drop, in the presentinstance, would be the drop ot the magnet LLC; IVe prefer to employ avibrating 0r continuous ringing bell, which will ring as long as thelocal circuit is closed, as by this means the attention of the operatoris imperativcly called to the out of order condition of the circuits. Inpractice, the magnets lc to 4c inclusive and the magnets cl3 c, togetherwith the push buttons s to inclusive, are preferably mounted upon aboard inclosed within a case, which we prefer 1o designate as the testcase, while the relays l to et and la to hlt inclusive, theelectromagnets lb t0 #Ib inclusive, the magnet am, the time operatedcircuit controller A, the signal transmitting mechanism, the relay b2and the magnets of to a, we prefer to locate within one of the largevaults, preferably the main or steel vault, within a suitable cabinet,and for the best disposition we prefer to arrange the signaltransmitting mechanism, its starting magnet, the relay d and the gangswitch, within a separate case provided with a door. which, when closed,acts upon the roller Z325 of the cross bar Z124 forming part of the gangswitch, and moves the switches into their full line position shown inFig. l0, butwhich door when opened permits the switches to beautomatically moved in the direction indicated by arrow GO to completetheir circuits forexhibition purposes. Vithin the second cabinet, weprefer also to locate the registerB and the time stamp B2.

In security vaults as now commonly constructed, the different vaults areusually located in a chamber provided with what is technically known asan iron grill having a door constantly guarded bya watchman. One featureof this present invention consists in providing a door ot' the grillwith an electrically actuated lock7 in addition to the usual manuallyoperated lock, which electrically actuated lock is represented in Fig. 1as a bolt g, located within a suitable casing or framework g', andsliding in bearings in one side of the casing and in the standard g2,and provided with a lug or projection g3, which is normally engaged bythe hooked end of an armature g4 of an electro-magnet g5, also locatedwithin the case g. The bolt g, as herein shown, is provided with asecond lug Q6 between which and the upright g2, the said bolt isencircled by a spiral` spring g, which acts to throw the bolt out of thecase and into a suitable socket in the door, when the electr0- magnet g5is energized and the door is in its normal position. The case g isprovided with a keyhole gT, through which which a key may be inserted toreturn the bolt to its normal position. This key will be kept in thepossession of the superintendent or other authorized person.

The purpose of the electrically controlled lock for the door of thegrill is, to ati'ord a double security both at night-time when the bankor vault is closed, and also during the day-time, and to effect thisresult, the electromagnetg5 controlling the operation of the bolt isconnected in a local circuit provided with a local battery g3, andhaving as herein shown two branches, one of which is connect- IOO IIO

ed with the armature Q9 andthe front stop Q10 of the relay or magnet@14,fand the other bran ch of which is connected to suitable manuallyoperated circuit controllers or push buttons Q12 Q12 Q14. As representedin Fig. 1, the local battery Q8 has one pole, as for in` stance, thepositive pole, connected by Wire Q15 to the front stop Q10, auditsnegative pole connected by Wire Q17'to one coil of the electro-magnetQ5, the other ycoil of which is connected by Wire Q18 to the armature Q9of the relay @14. The circuit controllers Q12, Q12, Q14 have one memberconnected by branch wires Q12, Q20, Q21 to a wire Q22, connected to theWire Q15 leading tothe positive pole of the battery Q8, and the othermembers of the circuit controllers Q12, Q12, Q14, are connected by wiresQ25, Q24, Q25, to a Wire Q26, connected tothe Wire Q1S leading to thenegative pole of the battery Q5. It will thus be seen that the operationof the electro-magnet Q5 is both automatically and positivelycontrolled, it being automatically controlledby the relayorelectro-magnet'a14, and positively controlled by one of the circuitcontrollers Q12, Q14 inclusive. The relay @14 is energized by theclosing of the circuit of the starting magnet for the signaltransmitting mechanism, through .one of the armatures of the circuitrelays 1 to 4, inclusive, and it will thus be seen that if one of thecircuits connected With the vaults should be opened during the time inwhich the system is under the control of the police, the relay @14 willbe'energized by the closing of the circuit including the starting magnet@5, and Will attract its armature Q9 and bring it into engagement withthe front stop Q10, thereby closing the circuit of the magnet Q5 andlocal battery Q5, and automatically releasing the bolt Q, permitting itto be shot intoits socket by the spring Q6 or in any other suitablemanner.' The local circuit when closed by the armature of the relay @14may be traced as follows: from the positive pole of the battery Q8 bywire Q15, front stop Q10, armature Q9, wire Q12, magnet Q5, wire Q17,back to the batter lxt it should be desired to quickly lock the door ofthe grill at any time during business hours and from a remote or distantpoint, one of the circuit controllers Q12, Q13, Q14 may be manuallyoperated, as for instance, the circuit controller Q12 may be located inthe. superintendents office andmay be closed at that point to energizethe magnetg5. The circuit in this instance may be traced from thepositive pole of the battery Q8 by wires Q15, Q22, branch wire Q12,through the circuit controller Q12, branch wire Q23, Wires Q26, Q12,through the magnet Q5 and thence by wire Q17 to the negative pole of thebattery Q2. In practice, it is designed that the manually operatedcircuit controllers, which may be of any desired number, shall bedistributed throughout the bank orother institution at the mostconvenient and desirable places. y vIn order that the operation of thesytein' `to transmit an alarm tothe police station may be understood,"let it be 'supposed that the operator has tested the various circuitsas above described, and that the wedged on the drop @41 controlled bythe electro-magnet c45, is in engagement with the circuit terminals'@26,a27, audthat the gang switches are in the positions shown in thedrawings; In this instance, let it be supposed that an attempt is madeto enter a vault having its door included in the No. 1 circuit, that is,inthe circuit of the relays 1 and 15, which vault may be supposed tobethe silver vault. As soon as au attempt is made to turn the usualhandle of the door, which latter maybe supposed tobe the north door, thebolt mechanism 168 is removed from engagement with the movable members60, 61, 62 of the circuit controllers governing the said door, and thelatter are immediately removed from their cooperating members 63, 64,65, thereby causing a break in the circuit of the relay l, demagnetizingthe said relay and permitting its armature 16 to be brought in contactwith its back stop 6, thereby closing the circuit of the magnet a5,which circuit may be traced as followsz-#from the positive pole of thebattery a7 by wire 0,17, terminal @19, wire 0,22, terminal @21,.wire@24, wire'lO, back stop 6, armature 16, branch wire 20,Wire @25, toterminal @25, through the wedge @L40 to terminal @27, thence by Wire @22to members a2 @20 of the circuit controller A, thence by Wire @51 toterminal @22, thence by the wire @24, terminal @2, Wire @2, through themagnet a5, wire Q12, magnet @14, Wire @15, to terminal 01,15, thence bythe wire 0,22, terminal d20 and Wire @18, to the negative pole ofthebattery. As soon asthe 'circuit just described, is completed by thearmature 16 of the relay 1, the magnet a6 attracts its armature @5,thereby releasing the motor mechanism of the signal transmittingmechanism. The break-wheel ci, in the present instance, is representedas provided with raised teeth or projections, and as each tooth on thesaid wheel comes in contact with the terminal bethe circuit of the relay5510- cated in the main orsteel vault, is opened, as is also the circuitof the bell magnet 547 and register magnet 550 located in the policestation. Each opening of the circuits of the relay 53 and the magnets547 550 is recorded, not only within the police station, but also uponthe registers B B in the main or steel vault andy the superintendentsoffice, and the timeat which such message is recorded, is marked upon astrip of paper as indicated in Fig. 11, the receiving apparatus in thepolice station being also preferably provided Witha time stampmechanism, and not herein' shown. The circuit of the relay 55 may betraced as follows, vizz-from the positive pole of the battery 58 by wire59, terminal 57, wire 55, terminal 55, wire 54, relay 52, wire 52,contact pen 5, penb, Wire 512, Wire 513, terminal 515, switch 517, wire540, through the cut-out 541, thence by the branches 542, 54E1 to themember 544 of the key `K Within the police station, thence by IOO I'Io

the member i945, wire 546, bell magnet b", wire 7119, register magnetZ250, wire Z951, to the ground G', thence to the ground at the bank, andby wire 7110 to the negative pole of the battery. At each opening of thecircuit referred to, occasioned by a tooth on the break-wheel a, thesaid opening is sounded upon the bell 61B and is recorded upon the stripZ252 of the police register in a short mark, after the manner indicatedon the tape C22, Fig. 1l. In order that the record at the police stationmay be made at each opening rather than at each closure of the circuit,the stylus or marking pen 654 is mounted on an arm 100 (see Fig. 10)pivoted as at 101 and adapted to be turned on its pivot by the armature7955 of the magnet 650. The stylus is removed from the recording tapeZ152 at each closure of the circuit by the spring or arm 102, which issecured. to the armature 1953.

Another feature of this invention consists in connecting the differentcircuitsiand batteries comprising the system to circuit terminals on acommon switch board, whereby different combinations of the circuits maybe cifected, as for instance, in one order or arrangement, one vault maybe included inNo. 1 circuit, a second vault in No. 2 circuit, a third`vault in No. 3, a fourth vault in No. 4, duc., and in another orderorarrangement, the vault previously connected in No. 1 circuit, maybeconnected with No. 4 circuit, and in another arrangement, two vaults maybe in. eluded in No. l circuit. This combination or arrangement ofcircuits is illustrated in part in Figs. 5 to 7 inclusive.

In Fig. 5, we have represented the circuit controllers 60 to 65 and 70to 75 of the silver vault, connected in circuit with the relays 1, 1a ofthe battery d10, and the circuit controllers 71,8, 72,9, 71,10 of adifferent vault, which may be supposed to be the granite vault, asconnected in circuit with the relays 4, 4, and a battery 7L. In thisarrangement, the No.1 circuitis the same as that shown in Fig. 1. TheNo.4 circuit may be traced as follows, viz:-from the positive pole ofthe battery 7L by wire 71,', terminel 72,2, wire` h5, terminal 72,4,wire h5, to terminal 72,5, thence by wire 72,7, circuit controllers7L8,.7t9, 71,10, the same being supposed to be closed'by the bolt `workof the vault door, thence by wirer7z1O0 to terminal k12, wire 7L15,terminal h1, wire 7115, relays 4, 4, wire 7115, to terminal 7L, thenceby wire 71,18, terminal h1", wire h2o, terminal` b21, and wire 7t22 to`the negative pole of the battery.

In Fig. 6, the circuit controllers h5, 77,9, 72,10 of the granite vaultare connected in the No. 1 circuit including the relays 1, la, and:.bat-` terydw, while the circuit controllers of the silver vault areconnected in the No.4 circuit; and in Fig. 7, the circuit controllers ofboth vaults are connected in` the No.1 circuit, `while the N 0. 4circuit is connected directly tothe battery 7L and is practicallydisconnected from the system. In practice, it might occur that one ofthe circuit batteries should become run down, and in this emergency, theweakened battery may be disconnected at the switch board and a fresh orauxiliary battery 7c vmay be instantly connected with the circuit, whichwould otherwise be disabled, thereby avoiding loss of time in placingthe otherwise disabled circuit in operative condition.

In Fig. 8, we have represented the auxiliary battery 7o as connected tothe No. 4 circuit, when arranged to include the relays 4, 4, and

`the circuit controllers hs, hf), 71,10, after the `manner shown in Fig.5.

In this instance, the positive pole of the battery 7a is connected bywire 7c to the terminal 7a2, joined by wire 7a3 to the terminal 71,4,while the negative pole of the battery 7c is connected by wire 761 tothe terminal 705 joined by wire 705 to the terminal 7t19, the rest ofthe circuit No.4 being the same as shown in Fig. 5. As above described,the wires of the system lead to a switch board w10 and the arrangementof circuits represented in Figs. 5 to.7 is eifected by changing theconnections of the different terminals on the switch board. This switchboard is preferably located within a suitably-locked ease, the key ofwhich is in the possession of the superintendent. In order to preventunauthorized access to the switch board, and thereby prevent shortcircuiting of the relays governing any particular vault, the said switchboard is located within the said case, not herein shown, but which has asuitable lock m (see Fig.l 15) the bolt m of which forms one member of acircuit' controller for the switch board case, the other member of thesaid circuit controller being preferably formed by a spring arm m2,secured` to a stationary support m3 which may be a part of the case, thesaid spring arm having secured to it an arm, rod, or projection m4, withwhich co-operates a 4stud or projection m5 on the back of the switchboard @10, the latter for the best results, being hinged or pivoted tothe bot-torn of its case, and the removable wires by which thedilferentcircuit terminals are connected together, being attached to theback of the switch board. By this construction, it will be seen that theswitch board must be turned forward in order to gain access to the wireson its back. In the normal rposition of the switch nboard the stud m5`acts on the rod 'm4, and presses the spring arm m2 away from the circuitterminal or member fm', thereby opening the circuit in which thecontroller is placed. The members m2, m', of the switch board circuitcontroller are connected to the branch wires a L15 connected to thebattery a5 through the starting magnet 0,6 Yand magnet 0,14, so that if`the switch board is turned forward into the po- IOO IIO

sition shown in Fig..15, the spring member I m2 will move forward, andlengage the terminalm, therebyclosing the circuit of the battery a7 andsetting the signal-transmitting mechanism in operation, besidesoperating the lock of the grill. lVhen the switch board 0,10 is in itsnormal or upright position, the stud m5 strikes the projection m4 andforces the spring arm or terminal m2 away from the terminal m.

To facilitate the description and to enable the electrical connectionsof the various circuits to be more easily traced, the switch board d10is represented in the drawings by a number of boards, which, inpractice, may and preferably will be one board.
